An evening argument is said to arrive at around 6.05pm, when family members have a remote control battle.

Another row erupts on average at 7.25pm, with grandparents attempting to start a game of charades.

Arguments are also said to occur at approximately 10.15pm before bedtime.

Relationship psychologist Corinne Sweet said of the results: "It's not only the turkey that gets overheated at Christmas - family flare-ups are inevitable.

"This is because people who rarely see each other are suddenly thrown together for the whole day. But the most important thing on Christmas Day is to relax and have fun.

"Make your expectations realistic and appreciate the time spent with your family."
